Question

calculate the number of Male in 20g of h2o​

Answer 1

Answer:

Hence,number of moles in 20g of water is 1.11111......

Answer 2

Answer:

Number of moles,n=m/M where m=given mass

and M=Molar mass

So,molar mass of water(H20)=2×1+1×16=18u

Hence,n=20g/18u{m=20g(given}

=10/9

=1.11111....

Hence,number of moles in 20g of water is 1.11111......
